This program initializes variables for student information and test scores, collects user input for name, course, and exam grades, calculates the course average, displays all stored values, and outputs the letter grade based on the course average according to specified grading criteria.

Paper For Above instruction

The following Python program is designed to facilitate the input, calculation, and display of a student's test scores and course grade. It begins with a standard comment header that includes metadata such as the assignment title, author, institution, course, instructor, semester, and date created. This structured documentation assists in maintaining clarity about the program's purpose and origin.

First, the code initializes variables to empty or default states: two string variables, name and course, are set to empty strings, while four numeric variables representing the exam grades—excelMidterm, pythonMidterm, excelFinal, and pythonFinal—are set to zero. This establishes a clean state before user input collection.

Next, the program prompts the user to input their name, course name, and the four test grades via the input() function. The grades are converted to floating-point numbers to accommodate decimal grades, allowing for more precise scoring.

Once all inputs are received, the program calculates the course average by summing the four exam scores and dividing by 4, storing the result in a variable called courseAverage. This calculation provides a simple mean score that will be used to determine the student's letter grade.

Following the calculation, the program outputs each variable's value with explanatory text, making the output user-friendly. This includes printing the student's name, course, each exam score, and the course average.

Finally, the program employs a series of if-elif-else statements to assign and display a letter grade based on the course average. The grading scale follows standard conventions such as A for averages 90 and above, B for 80-89, C for 70-79, D for 60-69, and F for below 60. Each condition is checked sequentially, and the corresponding letter grade is printed to the screen along with the numeric average.

Semester: Fall 2018


Date Created: [Insert date]


Initialize variables


name = ""


course = ""


excelMidterm = 0


pythonMidterm = 0


excelFinal = 0


pythonFinal = 0


Collect user input


name = input("Enter your name: ")


course = input("Enter your course name: ")


try:


excelMidterm = float(input("Enter your Excel Midterm Grade: "))


pythonMidterm = float(input("Enter your Python Midterm Grade: "))


excelFinal = float(input("Enter your Excel Final Exam Grade: "))


pythonFinal = float(input("Enter your Python Final Exam Grade: "))


except ValueError:


print("Invalid input! Please enter numeric values for grades.")


exit()


Calculate course average


courseAverage = (excelMidterm + pythonMidterm + excelFinal + pythonFinal) / 4


Display the stored values


print("\nStudent Name:", name)


print("Course:", course)


print("Excel Midterm Grade:", excelMidterm)


print("Python Midterm Grade:", pythonMidterm)


print("Excel Final Exam Grade:", excelFinal)


print("Python Final Exam Grade:", pythonFinal)


print("Course Average:", courseAverage)


Assign and display letter grade


if courseAverage >= 90:


letterGrade = 'A'


elif courseAverage >= 80:


letterGrade = 'B'


elif courseAverage >= 70:


letterGrade = 'C'


elif courseAverage >= 60:


letterGrade = 'D'


else:


letterGrade = 'F'


print("Letter Grade:", letterGrade)
